3.4 Dutch Sick Leave: What Managers Can Ask: ICS Payroll Guides Compliance

The moment an employee calls to report sick, a manager faces pressure to extract information needed for work planning. But Dutch employment law creates clear boundaries: managers can ask certain questions and absolutely cannot ask others. Getting this right in the first sick call sets the tone for compliance. ICS Payroll, as the legal employer under its EOR model, removes the guesswork by coordinating the formal sick-leave process on behalf of the hiring company.

What Managers Can Legally Ask During a Sick Call

When an employee reports sick in the Netherlands, the manager can ask for three specific things. First, an expected return date: this serves workforce planning and is explicitly permitted by Dutch law. Business.gov.nl says employers can ask for an expected return date. Second, logistical questions about ongoing work or handover needs, such as whether someone will cover the employee's responsibilities. Third, whether the employee needs occupational health support or whether they are able to work modified duties from home during recovery. This distinction is crucial: the focus shifts from diagnosis to practical recovery planning and work logistics. A manager might also ask whether the employee is able to work from home with light duties during recovery, a reintegration question that shows compliance with the law's expectation of early occupational health contact.

An expected return date is an estimate, not a commitment, and the employee may recover faster or need to extend the absence. But the question is permissible because it serves workforce planning. ICS Payroll, when acting as legal employer, ensures the occupational health coordination happens automatically, so the manager does not need to manage that detail in the initial call.

What Managers Cannot Ask Under Dutch Law

Dutch law explicitly prohibits asking for the specific illness, the diagnosis, the treatment plan, or the cause of the inability to work. Business.gov.nl says employers cannot request specific illness details or the cause. A manager cannot ask what is wrong or what the doctor said, or any variant that seeks medical information. Many foreign managers find this surprising because it differs from practice in other countries. The logic is occupational health protection. Medical assessment belongs with qualified professionals, not with managers.

The employer must have a basic contract with an occupational health and safety service or company doctor, and remain responsible for the contract's contents. That professional relationship, not the manager-employee conversation, is the channel for medical information. Volunteered health information must be handled with strict confidentiality. The employer must not record, store or share medical details that the employee mentions during a sick call. ICS Payroll's role as legal employer ensures this boundary is respected and documented consistently across all absences.

The Compliant Approach for Foreign Managers

A manager working for a foreign company with Dutch employees should follow this simple framework. Start with confirmation: I have received your message that you are unable to work today. Then ask the planning questions: Do you expect to return tomorrow, or should I plan for a longer absence? Then listen. If the employee volunteers information, the manager should simply acknowledge it briefly and move forward without asking follow-up medical questions and without recording the health details. This approach is compliant, professional, and respects the employee's privacy.

After the call, the manager should report to the payroll or HR administrator that the employee is absent and what expected-return date was given. The payroll provider or occupational health service takes it from there. ICS Payroll, operating as the legal employer when appointed in that capacity, handles the formal sick-leave process management, documentation, occupational health coordination, and compliance tracking. The manager's job is simply to take the call and record the essentials.

Why the Legal Boundary Exists: Occupational Health and Reintegration Duty

The Dutch employment law framework puts medical questions in the hands of occupational health professionals and makes it the employer's legal responsibility to arrange occupational health services. The employer must have a basic contract with an occupational health and safety service or company doctor, and remain responsible for the contract's contents. That professional is trained to assess fitness for work, advise about accommodations, and coordinate recovery. Tasks a manager is not qualified to perform.

By prohibiting direct medical questioning, the law encourages early engagement with the occupational health service. After a certain period of absence, the occupational health service must be contacted to assess whether the employee can resume work, work modified duties, or needs further rest. Managers who try to play doctor by extracting details delay that process and risk liability if health information is mishandled. ICS Payroll's EOR service includes statutory sick-leave coverage backed by insurance, which means the provider also carries the compliance risk and coordinates the occupational health process as the employer's partner.

Recording and Data Handling During a Sick Call

When an employee reports sick, the manager should record only: the date and time of the call, the expected return date (if given), and any non-medical logistical facts. Do not record diagnosis, treatment, medication, doctor appointments, or test results. If the employee mentions these details, acknowledge the information but do not retain it in written notes or email records. All employment law content pertaining to sick-leave procedures is reviewed and fact-checked by labour law lawyer Zishan Hussain, the firm's lawyer responsible for employment contracts, CAO application and dismissal law. This matters because data handling during sick leave is sensitive. Incorrect recording can trigger labor disputes and data-protection claims.

When ICS Payroll acts as legal employer, the provider maintains compliant records according to Dutch law, and managers are guided to record only the essential facts, not medical information. This removes the compliance burden from individual managers and centralizes responsibility with a provider that has the expertise and insurance to handle the legal risk.

What Happens After the Initial Call: The Occupational Health Coordination

Once the payroll or HR administrator receives notice of the sick call, the formal process begins. ICS Payroll, when acting as legal employer, coordinates with the occupational health service, ensures the employer meets its statutory reintegration obligations, and processes salary continuation. For a foreign employer using an EOR service, the administrator coordinates these steps. The manager's role is complete after taking the initial call and recording the expected return date.

The occupational health service will contact the employee at the employer's request (with the employee's consent) to understand recovery progress and whether any workplace accommodations or phased return to work is appropriate. The manager might not be involved in this conversation at all. This separation of roles, where the manager takes the call and the professional handles health coordination, is what Dutch law requires and what payroll providers like ICS Payroll are designed to support.

The boundary between permitted and prohibited questions is not a suggestion. Dutch labor inspectors audit sick-leave procedures, and violations of data-handling rules trigger GDPR fines. The correct approach is simple, documented, and scalable. For a practical walkthrough of the employer obligations during absence, see the employer obligations during absence.
